To all whom it may concern: I Y .Be it known that 1, MAX HERSKOVITZ,citizen of the United States, residing at Chicago, in the county ofCookand State of sitionsrelative to the part'wliich supportsthem,preferably to cause bulbs carried thereby to extend downwardly orin either direction in a substantially horizontal plane.

Other objects are to provide a'novel, simple and inexpensiveconstruction by which the supporting of the sockets, as stated, may beaccomplished; to provide a new and improved form of combined housing forthe electric wires and support for the socket, or sockets, which shallbe strong, durable and ornamental and may be used in a variety, of

locations and used with -either of its wirereceiving tubular portionsuppermost and other objects as wil-l be manifest from the followingdescription.

Referring to the accompanying drawings Figure 1 is a view in elevationof the upper end of-a socket-supporting structure pro vided1with aplurality of bulb-receiving sockets and embodying my invention, showingthe sockets in a position "in which the bulbs supported therein, andshown by. dotted lines, assume a depend ng,po u

'FigurelO is a-View like Fig. 1 of amodification ofthe structure shown-in the precedingfigures. Fig. 11 isan enlarged view in sectional elevation of thestructure shown in Fig. 10, one of the bulb-receiving I sockets beingomitted and Fig. 12 is a plan v ew of the lower housing-section of the-.Referring to. the construction shown in F igs. 1 to 9 nclusive',myinvention isshown as embodied inan electricsocket-supportingstructureof the type involving a base-(not shown) at which the structure isadapted to be supported, as for example, on'a table ora floor, with astandardrising therefrom and supporting"adjacentj'its upper end theupright or standard portion which is shown as made .of a'tube, asrepresented at 8, tl'iistube not only serving as a support but alsoserving 2 to enclose the electric-current-conducb' in'g wires which leadto the bulb-receiving sockets hereinafter referred to. The upper endofthe tubular upright 8 is secured to a housing member-representedgenerally at 9,

as by screwing the member 8 into tho holl'ow depending boss-portion 10of thehousing 9. The boss member 10 is provided as a part of aring-shaped'member 11 which is'formed,

preferably. integrally with an upwardly-ex tending b0ss12, preferably inverticalaligm ment with theboss 1 0. Tlhe-housing portion 9 alsocomprises cap-plates 13 of gener'alr dish'shape, as shown, preferablyof=semi-- spherical. form, which are adapted to be as sembled with thering-shaped member 11 at the opposite ends of the, opening therethrough, in a manner hereinafter described, to complete the housing andcause the latter to be of substantially spherical form as provided atopposite faces with annular res cesses 14-for receiving the marginaledges of the sections .13 in the assembly of the lat-" ter with theringmember 11, as shown in Figxqo. -The ring member 11 containsdiametrically opposed radially extending openings :15 which arepreferably horizontally disposedk l .5

Thecap sections 13 are each providedwith a recess portion 16 forming abottom wall 17 extending substantially parallel with the The ringmember. 11 is preferably axes of the openings 1 5,.these portions 16being preferably provided by deflecting the metalof these cap sections,the recess 16in one cap section extending ad acent to the part in {whichone -of the openings is ..lo.

cated and the recess 16 in the other cap section extending at the opposte side of the structure, all as shown in Fig. 5. The cap sections 13are removablyl ield in place'on prising, hollow shells 21 eachfprovidedwith the member 11, in the position above stated;

by screws 18 which extend through "openings in the portions 17 oftheOELPSBCQIOIIS .13 and screw into threaded openings 19 m the meme ber 11.i I

The bulb-receiving'sockets of the structurearerepresented at 20, thesesockets coma;hollo'w g0ose1-neck portion 22 openinginto theshells21through the ends of the latter. The. other ends of the goose-necksextendat an angle, preferably a right angle, to the longitudinalaxis ofthe shells 21 andare providedwith shoulders 23, shown as of annular,form, jand set back from-the extremities of these .endyportions,these-shoulders being shown as formed .by expanding :the' metalfformingthese goose-necksat said por tions. The portions of the goose-necks-justrefe-rreclto,1a11d which extend into the openings 15, and are rotatabletherein, contain peripheral grooves 24-shown as extending throughout aportion only of the circumfer ences of the gooseenecks and affordingshoulders 25 and 26 at'oppositeends thereof, the various parts being:so. arranged that the screws '18 when screwed to, a position in whichthecap sections 18 are held in place on the-ringmember '11 will extend attheir inner ends into the respective grooves 2 1,

- thereby holding the socket members against accidentaldisengagement-from the member 11, while permittingctr-the. independentro-v tation of thesocket members on this member, exceptas limited by thestops 25 and 26 which are provided primarily to prevent unduetwisting ofthe electric-current-conducting wires leading into the socketinembers.

The provision of the grooves 24,:of the a length shown, adapts thesocket members to be swung'from .a substantially vertical position tosubstantially horizontal positionand vice versa.

Thegooseneck portions 22 areeach prefenablyjformed of two sections ofsimilar shape and size and each of seini circular shapeincross-sectionwhich extend in edgeto -edge abutting relation, theseivsections being united along their'abutting: edges, if desired,;bysolderlng them. It is preferred thatatzthe ends thereof at whichtheyextend through the end-walls of the socketshells 21 the metal bespunto'interlock with the inner, surface of the shellsas shown .at 22 in-Fig. 9, .thegoose-necks above the shells 21 beingaprovided-withshoulders 23. The

contact .27 anda center contact 28.

socket-portions 21 preferably connect with the goose-necks between theends'ot the latter to render :the structure rigid, as repre--' sented at21 this connection, as. shown, b.e-'

ing, formed by stamping a'tub'u lar extension 21 from'the metal of thesocket 21 to fit atv its endagainstthe adjacent sideof the I goose-neck,and filling the extension 21 with solder as represented, at 21 whichalso serves to solder atthis point the joint between the goose-necksections. I

y constructing the. gooseen-ecks {as ,"stated, they. may bemadeeconomically and: of relativelysmall diameter and" fastened securely Iin place.

.The socket members contain socketinteriors (not shown) 'in' accordancewith' common practice, these socket-interiorsbe ing of any suitableconstruction. andiafi ord ingcontacts for the lamp, and, .as shown,being formed with an outerscrew-threaded The wiresleading intothehousing; 9 throughsthe pipe 8fare represented at '29 and 30, thesewires extending into the interior of. themernber 11 ,wh'erethey ,areconnected with the wires 31, 32, 38 and 34 which are-threaded throughthe goose-necks 32 and connect with the terminals of thesocket-interiors.

The provision of the member 9:as.a hollow structureand formedof sectionsisdeprovision of: athreaded'ro'd 35which-screws into the upper boss 12andcarriestwo disks the rod being shown as provided" with anornamentalsection 38. By virtue ofthe adaptabilityof the rod 35.to its adjustmentup and down on the housing 9 and 1 the adaptability of the disks 36 and37 'to independent adjustment on the .rod '3'5,the structure ls adaptedto support shades at different elevations relative tothe :housing memberand in a manner to present an ornamental appearance. 1

By providing the hollow bosses 1O= and121 the structure infaybeassembled with the supportingstructure, shown in the drawings as anupright, either in'the position shown. or in inverted position, or wiresmay be led in through :bothof the bosses 10-and 12 as desired. While thestructure is shown as involving its supportfroma stand, itwill'ben'ea'dily understood that it may be embodied in a chandelier,1nwhich case the upper'boss 12 would connect with the part depending from36 and37 threaded'thereon, the upper'end of the ceiling and supportingthe'fixture, and the shade-holdingmeans, if used, would be connectedwith the lower boss 10.

In the construction shown in Figs. 10, 11 and 12 the body of thestructure, instead of being made as described of the construction of thepreceding figures, is formed of a lower cup-shaped member 100 havingadepending boss 101 corresponding with, the boss and an upper invertedcup-shaped section 102 which with the section 100 completes thebody-member. The section 100 contains a series otradially-disposedopenings 103 in its side wall, near its upper edge, for receiving theinner ends of thebulb receiving sockets 20. The section 102 isperipherally flanged, as represented at 104 and is apertured to receivescrews 105 whichscrews into and through, openings 106 in the section 102and into the grooves 24 in the goosenecks 22 and serving the samepurpose as the screws 18 of preceding figures. By this arrangement, itwill be noted, any desired number of socket-members maybe provided inthe housing. WVhile only two of such members are provided the number maybe increased, if desired, by providing as many of the openings 103, asdesired, to correspond with the number of the members 20 to be provided.The bushing 107- provided in the opening 108 in the top of the section102,-receives .the stem 1,09 corre- SpOlKl'lllg to the stem 35. Y

It Will be noted from the foregoing that a structure embodying myinvention may be economically mianuiactured, is simple'of construction,and the parts thereof maybe readily assembled.
